The SMC ITV2090-31F2BL5 is an electronic vacuum regulator designed for applications that require stable, proportional vacuum control through an electrical input signal. It belongs to SMC’s ITV2090/2091 series, a product family developed for stepless vacuum pressure adjustment, compact installation, and reliable repeatability in automated equipment. According to the series specification, the ITV2090 range is built for a regulating pressure range of -1.3 to -80 kPa, with IP65 equivalent protection, an operating temperature range of 0 to 50°C, and an approximate unit weight of 350 g.
For the configured suffix 31F2BL5, market configuration references identify this version as a 24 VDC model with a 0 to 10 VDC input signal, 1 to 5 VDC analog monitor output, G thread, flat bracket, right-angle 3 m cable, and 5 kPa display unit selection. These configuration details are consistent with the ITV2090 series code structure shown in the catalog and with distributor configuration listings for closely related ITV2090 coded variants.

What the ITV2090-31F2BL5 Does
The primary role of the SMC ITV2090-31F2BL5 is to convert an electrical command signal into proportional vacuum control. In practical terms, this means the regulator can adjust vacuum pressure continuously rather than switching only between fixed levels. That capability is valuable in machinery where suction force must be controlled with precision, such as pick-and-place systems, vacuum handling equipment, packaging lines, inspection machines, and delicate part transfer applications. SMC describes the ITV2090 series as enabling stepless control of vacuum pressure in proportion to an electric signal, which is the core advantage of this design.
Compared with conventional manual vacuum regulation, an electronic vacuum regulator offers better consistency, easier integration into control systems, and faster adjustment when operating conditions change. In automated production, this helps improve process stability. If a production line handles different materials, part weights, or surface conditions, the vacuum setpoint can be fine-tuned from the controller instead of being adjusted mechanically. That reduces setup time and supports higher repeatability across batches. The ITV2090 series also provides monitor output capability, allowing the machine controller to supervise the vacuum control status through an analog feedback signal.
Structural and Functional Advantages
One of the most useful features of the ITV2090-31F2BL5 is its compact format. SMC positions the ITV family as a compact and lightweight solution, and the approximate unit weight of 350 g for the ITV20 size class makes it suitable for modern machines where installation space is limited. A smaller regulator is easier to mount close to the point of use, which can improve response and simplify pneumatic layout.
The product is also suitable for industrial environments because the series is rated IP65 equivalent. This helps protect the regulator body against dust and water exposure under typical machine conditions. In addition, the specified ambient and fluid temperature range of 0 to 50°C supports use in a wide range of factory settings, including packaging lines, semiconductor-related auxiliary systems, material transfer equipment, and automated assembly stations.
The configuration of this model is another advantage. Based on the suffix decoding, the 0 to 10 VDC input is widely compatible with PLCs, controllers, and industrial analog output modules. The 1 to 5 VDC monitor output gives users a practical way to monitor operation and build closed-loop supervision into the machine design. The right-angle 3 m cable is especially useful where panel space is tight or where cable routing must remain neat and protected. The flat bracket simplifies mounting on equipment frames or panels.
Application Scenarios
The SMC ITV2090-31F2BL5 is well suited for equipment that depends on controlled vacuum rather than simple on/off suction. Typical applications include vacuum pick-up heads, robotic handling systems, automated feeders, electronics handling systems, carton and film transport, and workholding solutions for fragile or lightweight parts. Because the regulator can vary vacuum continuously, it is useful in processes where one product requires stronger suction while another requires a gentler holding force.
This model can also be advantageous in production lines that need recipe-based control. When the vacuum level is driven by an analog input signal, the machine can automatically switch between different vacuum settings for different products or operating stages. That supports smarter automation and reduces operator intervention. In systems where process consistency affects yield, the stability of a proportional vacuum regulator can help reduce handling errors, slipping, or excessive gripping force. Those benefits matter in industries such as packaging, consumer electronics, precision assembly, and laboratory automation. The ITV series specification shows strong control characteristics, including linearity within ±1% full span, hysteresis within 0.5% full span, repeatability within ±0.5% full span, and sensitivity within 0.2% full span.

Why This Model Is a Practical Choice
From an engineering perspective, the ITV2090-31F2BL5 offers a balanced combination of control precision, environmental durability, and integration convenience. Its vacuum regulation range is appropriate for many common suction-based automation tasks, while the electrical interface supports direct connection to standard industrial control hardware. The approximate 350 g weight also makes it manageable for compact machine frames and modular assemblies.
For buyers, this model is attractive because it is not simply a general-purpose pneumatic part. It is a functional control component that can directly improve machine accuracy and flexibility. For machine builders, it helps simplify pneumatic vacuum management. For maintenance teams, the standardized SMC ITV platform can make replacement and specification matching easier. For distributors and system integrators, it is a product that fits both new automation projects and retrofit work where precise vacuum regulation is required.
Conclusion
The SMC ITV2090-31F2BL5 is a compact, industrial-grade electronic vacuum regulator designed for accurate proportional vacuum control in automated systems. With a -1.3 to -80 kPa regulating range, 24 VDC power supply, 0 to 10 VDC command input, 1 to 5 VDC monitor output, IP65 equivalent protection, and an approximate 350 g unit weight, it is well suited for modern production equipment that demands precise, repeatable, and electrically controlled vacuum performance. Its configured features, including G thread, flat bracket, and right-angle 3 m cable, make it practical for real-world installation and system integration.
